CG Ultimate Bipe Setup

[Claude Marston]

I recently picked up a used Carl Goldberg Ultimate Biplane. Can someone
tell me the control surface throws, CG location and wing incidence settings.
Engine suggestions would be helpful.

Hi Claude

Nice plane, you're gonna love her!

CG
Between 2 inches & 1 inch forward of the leading edge of the rear aluminum
cabane.

Recomended Throws in degrees (from the book)
Gentle Aerobatic
Ailerons 10 12
Elevator 12 14
Rudder 15 23

Wing incidence - Both wings are set at 0 degrees

I fly mine on a Thunder Tiger 1.20. Way overpowered! I did some reinforcing in
key areas. Check all screws b4 every flight!

Keep us posted & Enjoy!

All these are taken directly from the assembly manual and/or blue prints.

Low High

Ailerons 10 12
Elevator 12 14
Rudder 15 23

These are in degrees and taken from the Assembly manual.

CG is between 2" - 3" aft of the lower wing leading edge.

Looking at blue prints and they show wing incidence at O degrees for both
upper and lower.

Hope this helps.

Your TT 120 must have lots of power. I fly mine with a YS120NC and it
is ok. In the wing it out video David Patrick flys his with the YS120. I
have never seen a TT 4stroker are thay better than YS?
